GEORGE P. HOPKINS, OF ALBION, NEW YORK.

COOKING-STOVE.

Specification forming part of Letters Patent No. 38,744, dated June 2, 1863; Reissued February 9, 1869, No. 3,289.

To all whom it may concern:

Be it known that I, GEORGE P. HOPKINS, ofAlbion, in the county of Orleans and *State of New York, have invented a new and Improved Cook-Stove; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1, is a side sectional view of my invention taken in the w, 00, Fig. 2. Fig. 2, a plan or top view of the same, the top plate of the case which contains the flues being removed.

Similar letters of reference indicate corresponding parts in the two figures.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents the fire-chamber of the stove, B, the oven and C, the flues extending all around it as shown clearly in Fig. 1.

D, is a magazine or coal receptacle which is fitted'in an upright case E, and is provided at its upper end with a lid F, connected at one end by a hinge or joint a. The flue O, extends upward behind the magazine D, and in front of the magazine there is a flue G, which communicates with the flue C, just above the fire-chamber A. The upper end of the flue C, is provided by a grating (Z, which prevents coal from passing into it when the magazine is filled.

H, is a door in the upper end of the case E, and through which the magazine is supplied with coal. When the door H, is opened for this purpose the lid F, is raised forming an inclined plane to conduct the coal into the magazine D, see red lines in Fig. 1. The flue G, is provided with a damper I, near its lower end and in the lower part of said flue just below the damper I, there is a tubular shaft J, which communicates with the external air at one end and is provided with a crank K. This shaft J, has a flangeor wing 0, attached to it extending its whole length and it also has a serrated or toothed plate d, attached to it at a point directly opposite to the Wing c, and the shaft is perforated with small holes which may pass through the teeth of the plate cl, or just above or below it. A supplemental damper I, may also be placed in the flue G.

The fire-chamber A, is made separately or detached from the other parts of the stove and is arranged in such a manner that it may slide or be adjusted in the stove. By

referring to Fig. 1, it will be seen that the upper end of the fire-chamber is provided with a horizontal plate f, which rests on the top of the oven B, and the lower part of the fire-chamber in which the grate g, is fitted rests on supports it. By this arrangement the fire-chamber may be adjusted more or less forward or backward and its capacity varied materially. The plate f, is perforated with holes i, to admit air into the upper part of the fire-chamber from the ash-pit j below. Air is also admitted into the upper part of the fire-chamber through the perforations in the tubular shaft J, see red arrows and this shaft when rotated serves as a means to adjust or feed the coal from the magazine D, into the fire-chamber as the shaft J, is at the upper part of the lower end of the magazine.

When the damper I, is open the products of combustion pass directly up the flue G, as indicated by the arrows 1, and when said damper is closed they pass around the oven B, as indicated by the arrows 2.

I would remark that the fire-chamber A, may be retained at any desired point by a pin is, at the top of the oven which may be fitted in any of a series of holes Z, in the plate f.

The lower parts of the magazine D, and flue G, are curved as shown in Fig. 1, so that they may have a proper relative position with the fire-chamber and admit of the lat-. ter being properly supplied with fuel and at the same time admit of a proper draft being afforded it.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. The tubular perforated shaft J, fitted in the lower part of the flue G. and provided with the wing 0, and serrated plate (Z, and placed in such position relatively with the fire-chamber A, and magazine D, to operate as and for the purpose specified.

2. The sliding or adjustable fire-chamber A, arranged as shown when arranged and combined with the flues'G, C, perforated shaft J, and the magazine D, as herein set forth.
